Understanding Your Curl Type: A Practical Guide to the 2A-4C System
The Andre Walker hair typing system explained in full. Learn about your curl pattern from 2A waves to 4C coils, plus why porosity and density matter more for product selection.
The bottom line: The Andre Walker hair typing system (2A-4C) provides a starting point for finding products and tutorials, but porosity, density, and strand thickness often matter more for choosing products that actually work. Most people have 2-3 curl patterns on their head simultaneously.

The Andre Walker hair typing system, created in 1990 by Oprah Winfrey’s stylist, remains the most widely used curl classification worldwide—yet it’s also frequently misunderstood.
Type 2: Waves Form S-Shaped Patterns
Type 2A
Type 2A represents the loosest wavy pattern: delicate S-shaped waves that are barely defined, with hair falling relatively straight from the root before gentle waves form towards mid-lengths and ends. This fine-textured hair lacks volume at roots and is prone to oiliness.
Product needs: Extremely lightweight volumising products; avoid heavy oils and creams entirely. Hold level: Light (mousses work better than heavy gels).
Type 2B
Type 2B features more defined S-waves beginning at mid-length with greater volume than 2A. The crown area tends to frizz, and texture ranges from medium to thick.
Product needs: Frizz control, anti-humidity formulas, light-to-medium hold styling products.
Type 2C
Type 2C shows well-defined waves starting from the roots, sometimes including loose ringlets. This thicker, coarser texture is highly frizz-prone and resistant to styling.
Product needs: More moisture than other Type 2s, stronger hold products, and humidity control. This type borders curly territory and often benefits from techniques used for Type 3.

Type 3: Curls Form Definite Spirals and Ringlets
Type 3A
Type 3A consists of big, loose spirals approximately the size of sidewalk chalk—shiny, well-defined curls with fine-to-medium texture. These curls are softer and easier to style than tighter patterns but prone to losing definition.
Product needs: Lightweight hydration, products that maintain definition without weighing down.
Type 3B
Type 3B features tighter spirals about the diameter of a Sharpie marker, with medium-to-thick density. Expect bouncy ringlets to tight corkscrews and significant volume.
Product needs: Deep hydration, products providing both definition and hold, and regular frizz management.
Type 3C
Type 3C (added by the natural hair community, not Walker’s original system) presents dense, pencil-sized corkscrew curls that are tightly packed with high volume. Strands clump closely together and require careful handling due to fragility.
Product needs: Rich moisture, leave-in conditioners essential, finger-detangle only—avoid excessive combing.

- Bouclème Curl Defining Gel (mid-range)—defines without crunch

Type 4: Coils Are the Most Fragile Despite Appearing Thick
Type 4A
Type 4A features densely packed, tight S-pattern coils about crochet needle size—springy, soft-textured coils that are fragile and prone to brittleness.
Product needs: Intense moisture, regular deep conditioning, gentle handling. Shrinkage: Approximately 20% of true length.
Type 4B
Type 4B shows sharp Z-shaped bends rather than defined curls—a zigzag pattern where strands bend at acute angles. This coarse or wiry texture is 70% more prone to breakage than other types.
Product needs: Deep hydration, sulfate-free products essential, co-washing beneficial. Shrinkage: Up to 50%.
Type 4C
Type 4C represents the tightest coil pattern with very tight micro-coils that often appear to have no defined pattern. Extremely delicate with fewer cuticle layers, this type experiences extreme shrinkage (50-75%, some sources cite up to 90%).
Product needs: Maximum moisture retention, weekly deep conditioning, minimal manipulation, and protective styling.

- Aunt Jackie’s Flaxseed Gel (budget-friendly)—elongating, reduces shrinkage

Common Mistakes by Curl Type
Type 2 Wavies
Type 3 Curlies
Type 3 curlies often brush dry hair (causing massive frizz), touch curls while drying (disrupting formation), use too much heat without protection, and pull hair into tight styles that cause traction damage over time.
Type 4 Coilies
Type 4 coilies most frequently don’t use enough moisture—the single most critical error. Other common mistakes include rough detangling, expecting length without understanding shrinkage, using scrunching and plopping techniques (which actually increase shrinkage rather than helping), and assuming thickness equals strength when individual Type 4 strands are often very fine and fragile.
The Limitations of Curl Typing
While knowing your curl type helps with finding tutorials and community support, porosity and texture matter more for product selection. Two people with identical 3B curls may need completely different routines based on whether they have low or high porosity hair.
Most people have 2-3 curl patterns on their head simultaneously. The nape often features tighter patterns than the front or crown. Multi-textured hair requires sectioning during styling and potentially different products for different areas—heavier formulas on tighter sections, lighter ones on looser areas.
